PHP eregi domain

purg · 16-02-2009, 12:15:35 PM

Any simple way to dig out just the domain without hlq?
www.test.co.uk

Ive also noticed $_SERVER['SERVER_NAME'] sometimes contains WWW. that needs stripping.

blar.domain.co.uk = domain
www.domain.co.uk = domain
domain.co.uk = domain

what bit do you want specifically? Just the 'test' in www.test.co.uk ?

Eregi for detecting domain names is crazy as http://www.i.am.adding.many.sub-domain.test.co.uk is a valid name, so it takes some fancy regex to detect all the varients, I wrote about 100 lines of code to do this and still had some name getting thru so I went with a quick and nasty snippet.

PHP Code:

  /////////////// START DOMAIN CAPTURE BLOCK ////////////////

    $domainz = substr($_SERVER['HTTP_HOST'], strpos($_SERVER['HTTP_HOST'], '.')+1);

    if (strlen($domainz) <= 6) {

        $domainz = $_SERVER['HTTP_HOST'];

        if($debug == true) { echo '<p>var $domainz - Length: ' . strlen($domainz) . ' - Value: ' .  $domainz . ' - Sub Domain: No</p>'; }

    } else {

        $domainz = substr($_SERVER['HTTP_HOST'], strpos($_SERVER['HTTP_HOST'], '.')+1);

        if($debug == true){ echo '<p>var $domainz - Length: ' . strlen($domainz) . ' - Value: ' .  $domainz . ' - Sub Domain: Yes</p>'; }

    }    

    //////////////// END DOMAIN CAPTURE BLOCK /////////////////

This works for most .uk names that I tested, if it was for a client I'd have my programming house write it but this was a parking script after I got spanked over my signature links :P

Have a look at

I posted a stack of code on my parking script, which I still havent finished or made look pretty :P

Whizz.... Correct

Skinner.... thanks for the link but:-
My draft looks similar to your snippet but caters and removes sub domain levels. Only failed style of domain would be two char hlq domains (xx.xx.CC or WS style of names) with one char subdomain.
I dont own any so not a problem for my needs.

PHP Code:

  $arr = array("/", "?", "%");

$pos = "256";

 
foreach ($arr as $findme) {

    if (strpos($_SERVER['HTTP_HOST'], $findme) !== false) {

        $pos = strpos($_SERVER['HTTP_HOST'], $findme);

        break;

    }

}

 
$pos = $pos - strpos(substr($_SERVER['HTTP_HOST'], $pos-6, 6);

$domname = substr($_SERVER['HTTP_HOST'], 0, $pos);

$domname = substr($domname, strrchr($domname,'.')+1);

 
echo $domname;

(untested)

Due to .ac, .com, .info, .travel, .museum, .whogizzafuck the scripts was all failing on full tests.

My original 100 line function, used a multidimentional array, where I exploded the URL on a period, then tested the highest element of the array against tld[x], then tested tld[x][y] on highest -1, to see if that existed on the second level, if it was a positive then I accepted url+tld[x][y]+tld[x], else I assumed url+tld[x], then I performed a DNS look up to test it, where URL = part -3 of the exploded url.

However it was a nightmare finding all the official subs to build the multi-dim and it slowed the script down doing look ups and stuff so I went all slasher movie and hacked it up

Jeewhizz · 17-02-2009, 03:38:54 PM

Goodness me. Either I'm not understanding this right, or you are all handling this wrong

The below code will take an array of domains in a variety of formats, and will get you just the domain element (i.e. no subdomains, no TLDs).

Let me know how you get on:

PHP Code:

  $domains = array("www.test.com","www.test2.co.uk","www.test3.info","www.test4.wz","www.test5.museum","http://test6.co.uk","test7.co.uk","http://www.test8.co.uk");

 
foreach($domains as $domain) {

    if(preg_match("/\.?([a-z0-9-]+)\.co\.[a-z]{2}$/i",$domain,$m)) {

        //we've matched a ******.co.** domain

        $dom = $m[1];

    } else {

        //treat the domain as a .com/net/org/ws/biz/info

        preg_match("/\.?([a-z0-9-]+)\.[a-z]{2,}$/i",$domain,$m);

        $dom = $m[1];

    }

    echo $domain.': '.$dom.'<br />';

}

Output for the above code:

Quote:

www.test.com: test
www.test2.co.uk: test2
www.test3.info: test3
www.test4.wz: test4
www.test5.museum: test5
http://test6.co.uk: test6
test7.co.uk: test7
http://www.test8.co.uk: test8

Whizz, we are talking about returning ONLY the domain.ext with no subdomains.

Checking if its a valid domain is easy, but slicing the www. or del. or whatever else off the end of the start of a domain is no easy task.

If you knew for a fact that you would only ever get www. you'd just reg replace, but on a parking script ideally you want wildcard sub domains but need a way to pull your database entry

Quote:

select * from domains where dom = del.icio.us
select * from domains where dom = http://www.icio.us
select * from domains where dom = http://icio.us
select * from domains where dom = v.icio.us

would all return different data and be useless for domain dependant data.

Now because the .ext's can be between 2 and 7 chars long and between 1-2 sections (.com vs .co.uk), it makes separating them hard work.

If you have a nice easy way I'd love to see it :P

I'm no PHP expert but surely Jees script does almost what you're asking, it currently returns the main part of the domain, without subdomains or the extension. You just need to alter it slightly to include the extension?

grantw · 18-02-2009, 12:05:41 AM

Also, again 'im no php expert' but can't you do this with explode?

Get the domain
explode it by "."
If the last part of the returned array contains "uk" then your domain with extension is made up of the last 3 parts of the array
If it doesn't contain "uk" the last two parts of the array are what you want

Or maybe I'm making this up as I go along
